IGNITION DEVICE FOR GAS-BURNERS.

Specification of Lettere Patent.

Patented March 10, 1908.

Application filed September 20, 1905. Serial No. 279,254.

To all whom it may concern:

Be it known that we, MAX BAER and PAH. FLAcusilA/m, subjects of the King of Prussia. lermanEmperor, residimY at Berlin, Dresdenerstrasse 86, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Ignition Devices for Gas-Burners, of which the, following is a full, clear, and exact descripic tion.

For igniting'burners on incandescent gas lights it is usual to have pilot lights. These p1 ot lights are arranged to either burn constently, or the same have .to' be siecially le lighted when the lburner is required to be lighted.' In those` of the last mentioned pattern the gas is 'shut ofi and only put on again as as the`lame is wanted. For tummlotie gais atwo-way cock is generally zo used t e f nufacture of which is known to be 'drlicult and expensive, and the cock has to be specially attended to, also causing loss of "as when not properly shut oil'. The present invention refers to an ar- ;:5 rangement for igniting gas burners. where the piletliglit is not constantly burning, but is on "iiiinted when the mam llame is require ffffi'o effect the aforesaid ignition an ignitipn pill is used, which through the escapzioin?, brought to a red heat` The gas is sim ci? from the pilot light by means of a and the same is only opened again to fl-valve give the pilot light the necessary quantity of `gas. The main pipe for the burner remains in the present invention always open.

The annexed drawing shows an ignition device for gas-burners constructed in accordance with the invention.

Into the cone a of the burner bis screwed the body or nipple c in which the main gaspassage is arran fed. On the side of said nipple is attache the side-tube d, on which is mounted the ignition-pipe c. At the upper end of the ignitionipe is the mantle in which the ignition-pelllet is contained l\ ovable in the gas-passage of the side-tube d is a Ai l) valve g the body of which is intended to be moved into the main gas-passage. Said valve. is provided with a spindle which extends through the side-tube and is u'ovided with an operating-knob and controlled by a spring, as shown.

'lo light the gas, the main pipe is iirst of all opened, when the spindle of the valveI is )ushcd down, to allow the gas to enter the )urner b and at the same time into pipe e towards the ignition pellet. The pellet now bevins to glow igniting the rising gas, which will also ignite the gas inside the burner.

To open the valve the s iindle is forced inwardly in the nipple or body c and at right angles to the main gas-passage, and the valve g is thereby caused to move away from its seat and permit the passage of leas to the. pilot-burner, said valve thus being pushed into the main gas-passa 'e and reducingy the cross-sectional area of t e same so that the flow of gas to the main burner is reduced. In this manner too much gas is not delivered to the main-tube, and there is no 'violent explosion when the gas-current is ignited.

What I claim as my invention and desire to secure by Letters Patent is:

The combination, with a gas-burner having a main Tas-passare in the body thereof, of a side-tu )o exten( ing lateralhT from said bodv and having a gas-passage leadingr lateral y from said mam gas-passage, an ignition-tube mounted on said side-tube and a valve to control said lateral gas-passage movable at right angles to the main gaspassagc and into the same when said valve. is opened, whereby the flow of gas through said main-gas )assauc is reduced.

In witness wliercol", we subscribe our signature, in presence of two witnesses.
